Position control sensing valve was stuck so got that freed up.Those little screws on the front of valve that hold the seal in sure can be a bugger to get out.Now working on the spool that my book calls the traction booster valve.This valve does not move freely, is it supposed to have four detents that corresponds to the four positions which are raise,hold,traction booster and lower? Thanks

Traction booster valve does not have any detents. The linkage holds it open when needed.

AC 180 / 185. Hydraulic control levers on right hand side of seat.

On most the front row has 3 levers and rear row has 2 shorter levers.

Front Row;

furthest right is for raising/ holding/ lowering 3 point lift arms.

left and center used to control the Remote Cylinders through the quick couplers, they have 4 positions each;

1. Back is pressure detented . 2. hold. 3. is pressure detented. 4. Forward is manually detented. ( pressure detents release when hydraulic pressure reaches set level)

Back Row; 2 short levers, these are not detented, can be moved to as needed.

Right is the Traction Booster Lever. Used to adjust load on lift arms when using a plow or similar implement.

Left is the Position Control Lever. Used to pre-set the lowest height of the 3 pt lift arms.

You'll want an Operator Manual to clarify how these 2 are used.
